| description |
A new equation has been derived using energy technique (dummy load method) to describe the buckling behavior of intermediate and long columns under dynamic buckling loads compression load and under dynamic combined load with consider of the initial imperfections of the columns and the effect of eccentricity. The results of this equation are compared with the experimentally results of 40 specimens of AISI 303 stainless steel intermediate and long columns tested under dynamic compression loading (compression and torsion) and under dynamic combined loading (compression, bending, and torsion) by using a rotating buckling test machine, and it be found that the derived equation may be used to predict of the theoretical critical buckling load Pcr under both dynamic compression and combined load with maximum percentage error is 19.3% and 16.8%, respectively.
